To all whom, it may concern.-

Be it known that I, MosEs LINKER, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and .useful Improvements in Bottle-Stoppers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bottle stoppers.

The object of the invention is to provide a bottle stopper so constructed that the upper fragile end of the bottle neck will be entirely covered and protected and the bottle hermetically sealed.

A further object of the invention is to provide a stopper of this character which may be quickly opened or closed by a slight turn of the arts, said stopper being simple, strong, durabl e and inexpensive in construction, eflicient and reliable in operation and well adapted to the purpose for which it is designed.

In the accompanying drawings :Figure 1 'is a side view of the neck or upper end of a bottle, showing the application of the invention Fig. 2 is a vertical sectional view; Fig. 3 is a top plan view of the same; and Fig. 4 is a similar view of the inner 'cap of the stopper.

Referring more particularly to the drawings, 1 denotes the neck of the bottle, on the upper end of which is formed an annular enlargement or head 2. Adapted to be fitted tightly upon the enlargedhead 2 of the bottle is an inner cap 3 having a flat top 4, in which adjacent to one side thereof is formed a discharge passage 5. Between the upper end or head of the bottle and the inner wall of the top 4 of the inner cap is arranged a washer 6 formed of any suitable material and having therein a discharge passage 7, which is disposed immediately below and in line with the passage 5 in the top of the cap.

On the inner cap 3 is arranged an outer cap 8. Said cap 8 is revolubly mounted on the inner cap 3, but is adapted to snugly "fit the same. The cap 8 is provided with a flat top 9, between which and the to 4 of the cap 3 is arranged a washer 10. In the top 9 adjacent to one side thereof is formed a discharge passage 12, and in the washer 10 immediately below the passage 12 is formed an alined passage 13.

When the parts are in closed position to seal the upper end of the bottle, the discharge passages 12 and 13 in the outer cap and washer will be disposed over the solid or imperforate part of the inner cap, as clearly shown in Fig. 2 of the drawings.

In order that the bottle may be opened to permit the discharge of the contents therefrom, it is necessary to revolve or turn the outer cap 8 together with the washer 10 which is adapted to rotate therewith until the passages 12 and 13 in said outer cap and washer are over or in line with the passages 5 and 7 in the inner cap and washer, at which time the contents of the bottle may be discharged or the bottle may be filled.

In order to facilitate the turning of the outer cap, the upper edge of the same is preferably milled or roughened, as shown at 14. In order that the movement of the outer cap may be limited to permit the turning of the same, a sufficient distance to bring the discharge apertures in the cap and washers into alinement, the inner cap 3 is provided on one side adjacent to its top with a segmental groove or recess 14 with which is adapted to be engaged an inwardly-projecting detent 15 formed in the side of the outer cap, as shown. Said detent limits the turning movement of the outer cap and stops the same at the proper position or when the discharge passages are in alinement as hereinbefore described. On the lower edge of the outer cap is formed an inwardly-turned annular retaining flange 16 adapted to engage the lower edge of the inner cap and thereby securely hold the outer cap in place.

A stopper or closing device constructed as herein shown and described will not only afford means for hermetically sealing the bottle but will also effectively protect the upper edge or'mouth of the bottle from being chipped or broken.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is

The combination with a bottle having a with an aperture adapted to register with the i aperture of the inner cap when disposed in one position and with its lower edge crimped beneath the lower edge of the inner-cap, said inner cap having a relatively long segmental indentation and said outer cap having a rela tively short indentation for Inovably bearing in the long indentation.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MOSES LINKER.
